The chloroplast size is about.
Correct answer: C. 4-6 µm
- A. 1-2 µm
- B. 2-4 µm
- C. 4-6 µm
- D. 6-8 µm
Explanation
Chloroplasts are a type of plastid. They are chlorophyll-containing organelles within the cells of plants and green algae that are the site of photosynthesis, the process by which light energy is converted to chemical energy, resulting in the production of oxygen and energy-rich organic compounds. They are enclosed in a chloroplast envelope, which consists of a double membrane with outer and inner layers, between which is a gap called the intermembrane space. Chloroplasts have a diameter of about 4 - 6 micrometers.

About Cytoplasmic Organelles
Cytoplasmic organelles are the specialized structures suspended in cytoplasm, including mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles and centrosomes. Questions compare their structures and functions in animal and plant cells, including chloroplasts and the role of the endomembrane system in transport and secretion.
